You're not wrong but your description is conflating two different things.
What you're describing - "pay what Medicare pays" is more or less how private insurance typically works for in-network providers. The provider gets paid X% of the Medicare Allowable Rate (where X > 100), and that comes either from the patient or the insurer (depending on any applicable deductible, copay, OOP max, etc.)
Reference-based pricing applies that to all providers, including out-of-network providers. However, except for care received in the emergency room, the provider is allowed to bill the patient for the difference between what the insurer allows and what the provider charges. Some plans will actually allow in-network providers to bill patients for the balance. In that case, everyone wins except the patient: the insurer/employer has a fixed cap on their costs per service, and the hospital/provider doesn't have to settle for a lower rate.
